Update JSDOM & ESLint to resolve security advisory

[aduth]

🛠 Summary of changes

Updates JSDOM & ESLint dependencies (and subdependencies) to resolve a security advisory related to the word-wrap dependency.

Upgrading the top-level dependencies was enough to resolve JSDOM. Upgrading ESLint did not automatically force an update to its optionator dependency, where optionator@0.9.3 swaps the offending package with an alternative, patched version. Removing the optionator block from yarn.lock and rerunning yarn install was enough to force the update.

📜 Testing Plan

The audit_yarn_package exits with a successful exit code:

make audit_yarn_package
echo $?
# 0

Upgrading JSDOM will require more work due to some issues with how we manipulate window.location that appears to have changed in newer versions (related issue). It will be nice to upgrade since it drops the dependency chain altogether (escodegen > optionator > word-wrap), but since at least the optionator package is in common, we can update to the newer version of that to resolve.

[aduth]

Actually, that might not be true, since escodegen uses an older, unpatched version of optionator 😖

I managed to work through the JSDOM upgrade, mostly by using a dependency injection approach to parameterizing the redirect logic as an alternative to stubbing the window values directly. This should be ready for another review.
